Study of the partial wave structure of π0η photoproduction on protons

Abstract

Analysis of the partial wave structure of γp → ^π0ηp reaction is presented in the energy region from threshold up to the total center-of-mass energy W = 1.9GeV. Angular distributions measured with the Crystal Ball/TAPS hermetic detector system at the Mainz Microtron MAMI are expanded in terms of spherical harmonics. The relation of the extracted moments to the partial wave structure of the reaction amplitude is discussed and compared with predictions from model calculations.
